具有距離自動修正的紅外溫度監(jiān)測儀的研究與實現(xiàn)
[Abstract]:In the electric power system, the temperature monitoring of electrical equipment is a very important work. At this stage, the main way of temperature measurement is contact-type temperature measurement, because of the problems of safety hidden danger in contact-type temperature measurement, etc. In this paper, a non-contact infrared temperature measurement method is proposed to monitor the temperature of substation electrical equipment, and an infrared temperature monitor with automatic range correction is designed. In this paper, the basic principle of infrared temperature measurement is introduced, and the main factors affecting infrared temperature measurement are analyzed. In order to reduce the influence of distance factor on temperature measurement, a method of distance correction compensation is put forward in order to reduce the influence of distance factor on temperature measurement. Then the basic principle of laser ranging is introduced. According to the actual requirements and existing conditions of the project, the overall scheme design and laser ranging scheme design of the system are put forward. Then the circuit design of the system, including microcontroller circuit design, ambient temperature DS18B20 temperature measurement circuit design, infrared temperature MLX90614 temperature measurement circuit design, laser ranging module circuit design, Interface circuit design and power supply circuit design; The PCB board of the system is drawn and welded. The program code of the system includes main control program code, environment temperature DS18B20 temperature acquisition program code, infrared temperature MLX90614 temperature acquisition code, laser measurement program code and man-machine interface program code. Finally, the software and hardware debugging work of the whole temperature measuring system is completed, and the main function of the infrared temperature monitor is realized. After testing, the system accords with the set performance index.
